Roor organic chemistry
WebKatherine Scott. Bromine has a negative charge when it has a full octet; this makes it an negative anion so it wants to bond with a positive carbocation. (Unlike charges attract) This is because, as posted above, a bromine atom is neutral when it has 7 valence electrons. If it has 8 v.e then it will have a charge of 1-. WebJan 23, 2024 · Step 1: Initiation Once the pre-initiation step involving NBS produces small quantities of Br 2, the bromine molecules are homolytically cleaved by light to produce bromine radicals. Step 2: Propagation One bromine radical produced by homolytic cleavage in the initiation step removes an allylic hydrogen of the alkene molecule.
